Factors affecting the surface temperature of steel ladle shell are steel smelting temperature, environment temperature and thermal resistance. 1.Steel smelting temperature. The increase in the temperature of molten steel led to an increase in the temperature of the steel ladle shell, but not obvious. In the general steelmaking temperature range, the resulting steel ladle temperature changes within 10℃. 2.Ambient temperature. When the outside temperature decreases and the temperature of the steel shell decreases. Generally the outside temperature decreases by 10℃, and the temperature of the steel ladle shell decreases by 5℃. Therefore, improving the external conditions could observably decrease the temperature of steel ladle shell. 3.Thermal resistance. The thermal resistance increases, the temperature of the steel shell decreases significantly, and the energy consumption decreases. Wanhao is a manufacturer who is specialized in designing vario...

Refractory motar is composed of refractory powder, bond agent and additive agent. Almost all refractory raw material can be used to make refractory powder to produce refractory morta. Ordinary refractory motar is made of refractory powder, adequate plastic binder and plasticizer. Its room temperature is low, the formation of high temperature ceramic bonding with high strength. The combination of hydraulic, gas hard or thermosetting binder is called as chemical bonding refractory clay, it is a formation of a certain chemical reaction and hardening before the formation of ceramic bonding temperature. Refractory clay particle size varies according to the requirements, the ultimate size is generally less than 1mm, and some less than 0.5mm or smaller. Refractory motar according to the composition of the different materials can be divided into: dry soil refractory motar, high alumina refractory mortar, Special refractory motar , magnesia refractory mortar.  Articl...

The conditions required for stable operation of blast furnace are as follows: 1. Good raw material quality, containing low harmful impurities, with good metallurgical performance. 2. The quality and quantity of raw material for blast furnace should be stable and balanced, and the production does not appear to cause the sintering, pellets. 3. The blast furnace foremen have high technical quality, high level operation of blast furnace, develop a scientific and perfect operating procedures (blast furnace needs standard deviation operation), no operational error basically, put an end to major accidents. 4. Achieve inspection, repair on time, shorten the equipment maintenance time, does not appear a major accident. 5. Respect the basic principles of metallurgy, the implementation of the scientific concept of development, do not appear management decision-making mistakes and blind command. 6. Able to maintain a long time of blast furnace reasonable profi...

During continuous casting, the   casting powder   is mostly used (together with submerge nozzle) except from casting billets with small section. Practice has proved that this process is one of the important conditions to ensure the quality and normal operation of casting billet. In the early 1970s, the process was successfully applied to slab continuous casting in our country and solved the problem of slab longitudinal crack, and then was gradually popularized and applied. In recent years, a series of protective slag has been established, Some special fluxes for continuous casting of special steel are developed, which provide necessary conditions for further development of continuous casting in China. There have many kinds of   refractory products in our factory. Function of   mold fluxes : 1 Insulation 2 Isolating air and preventing molten steel from oxidizing two times 3 Purify the slag interface and absorb the inclusions in molten steel 4 Lubricatio...
